I am getting a time out on controller to PC. Running windows 7. Upon start of cut it will run for a bit then time out. The torch will keep firing until I shut the plasma machine off. At that point I shut off the controller and back on to reset but then the table still won't respond.I have gone to settings and disabled the USB conserve and set the computer to performance. I also put on a new usb cable from the PC to controller. Any ideas out there?
